Okay, It's June 15. Where's the updated LOLA data? I keep finding the stuff from March in all the usual places. Okay, I'm sure it may take a few days, but does anyone have a clue if the LDEMs are going to get cleaner and crisper this time around?

I've already seen a resin casting of a moon globe made from the LDEM_64 data, but I wanted to wait a bit until more blanks were filled in.

Well, if it doesn't have .img or .jp2 stuck to it, I can't use it. It would be lovely to have, oh, a file with a name like LDEM_128.img . I am in no way smart enough to use anything else that I have been seeing with a June date on it. Yeah, I've checked with the PDS and Imbrium pages, and I'll wait until the image files "get good." Been spoiled by MOLA.

Right... some of the data releases are delayed a bit, and maybe place-holder files are online while preparations continue. These are very large and complex datasets, and PDS documentation is time-consuming.

On another note - LRO has been in orbit for a year. In a few months the orbit is due to be raised as LRO enters its extended mission phase under the Science Mission Directorate.

Use the ones with 0 as the least significant bit. It is interesting to understand the criteria for eliminating points. There are so many shots, that it is impossible to manually filter them all. The main automated filter they include is to compare the 5 shots against each other (not against other nearby shot sets). I think the slope limit is 37 deg between shots. This does a good job on most shots.

I have looked around both poles and found some that were erroenous comared against existing LOLA data from other passes (no shots have yet been manually editted/flagged in the RDR datasets so far). If you are interested in them, I can give you a list. It isn't that big and would likely not show up if you are using a tool like GMT to process the points into a DEM (unless you are shooting for high resolution) due to the averaging and surface fitting that tool uses.

An announcement from the PDS -- I don't know if this affects any of the work that you all are doing --

Yes, this will affect my work. Thanks.

I am baffled also by the lack of data density. I am waiting for LROC stereo imagery inferred heights correlated with the LOLA data. The problem is that LOLA, even at the poles, has <.3% of the surface area "painted" by LOLA light. Interpolations of height seem somewhat unreliable based on that. Normally, one could generate nice looking 3D models without worrying about this, but doing illumination analysis and being impacted by unknown nearby terrain or planning mobility paths can't be done with LOLA alone.

don't know yet the last update was to fix the errors in the .lbl files we have been finding " corrected minor errors in EDR and RDR data product labels "those errors the "time tags" ??? don't know but the derived image dost match up with Kaguyawill have to lookbut people might want to read the errata.txthttp://pds-geosciences.wustl.edu/lro/lro-l...1xxx/errata.txtthe relevant part

CODE

RELEASE NUMBER: n/aRELEASE DATE: 2010-07-20DATA COVERAGE: 2009-06-18 to 2010-03-22 (entire mission through 2010-03-22)PRODUCT TYPES RELEASED FOR THIS ARCHIVE: No new productsPRODUCT TYPES UPDATED FOR THIS ARCHIVE: EDR, RDRREASON FOR UPDATES: Data processing correction

The LOLA Team discovered and corrected a processing error that affected time tags in RDR data products from day 2010-02-15 onwards. The Team also corrected minor errors in EDR and RDR data product labels. This intermediaterelease consists of revised versions of all previously released RDR productsand their PDS labels, and revised EDR labels only (not data files). A revisedproduct can be identified by the keyword PRODUCT_VERSION_ID = "V1.03" in its label.

The following data files and corresponding labels, which were previously included, have been excluded for this and future releases due to poor data quality.
